Works well with H9i headphones
First impression is good - no problem with fitting the battery into H9i headphones, the battery life seems to be comparable with the original one.

Battery Replacement for B&O H9i headphones
Took seconds to fit, charged up and worked fine ... I guess we'll only know if it was worth the +£30 saving on an official B&O battery if it's still working in a couple of years from now!

A tad fustrating
The battery seats inside the headphone but isn't a proper fit and unable to close properly I have to tape over the lock but did manage to charge up to use on Bluetooth ..it works but for these particular headphone not quite the right fit

Der Akku (in Beoplay h7) hält bei hoher Lautstärke circa 5 Stunden, bei leisem Musik hören circa 10 Stunden! Vergleichbar mit dem Original Akku? Nein! Unbrauchbar? Ja!
